How Lamb Chop’s Creator Helped Shape a Star Trek Story

Shari Lewis was known to television audiences for Lamb Chop, the soft-spoken sock puppet she performed with. But her work also reached the writers’ room: she co-wrote “The Lights of Zetar,” an episode of the original Star Trek’s third season, with Jeremy Tarcher.

The episode builds its science-fiction premise around a remote Federation facility called Memory Alpha, where records and knowledge from across the Federation are stored. A strange force attacks the station, and the crew discovers that it is connected to the planet Zetar—and to Lieutenant Mira Romaine, who can sense the beings behind it.

The Story Turns an Idea Into a Personal Risk

The Zetarians are not simply an invading force. They are disembodied beings seeking a way to survive, and Romaine’s body becomes central to that effort. That choice makes the threat intimate: the crew must protect both a vast storehouse of knowledge and one of its own officers.

The setup also gives the episode a distinctly Star Trek tension between scientific curiosity and personal danger. The crew tries to understand an unfamiliar phenomenon even as each new discovery raises the stakes for Romaine.

Lewis’s writing credit is a reminder that a creator associated with a beloved children’s character could also contribute to a story about alien life, identity, and survival. The two kinds of television may seem far apart, but both depend on making an unusual character or situation feel vivid to an audience.
